I have just changed phone from an iPhone SE to an iPhone 15. None of my new activities are showing and I am not following any of my friends. It looks like I have to refollow people to get them to appear in my activity feed. The last time that a recorded activity is on my account is January 2021, there is nothing recorded since then, and I regularly exercise so there are hundreds of activities missing.
It’s clearly the switching of phones, old to new, but even after logging out of my other device I am not seeing any of my data
